You want ajax="false" if you want to have a synchronous request with a navigation. As to the update parameter, see my comment in one of your previous questions which you didn't respond to yet.

As to the enctype="multipart/form-data" issue, for that you need to ensure that you've configured the PrimeFaces FileUploadFilter as per the instructions in their User Guide.

@BalusC: Ah, and now I know where that enctype came from - the file upload turned out to be unnecessary, but the attribute stayed around to mess up things... Thanks!
